Choices
-0.5 meters/ per second^2
-1 meter/ per second^2
-2 meters/ per second^2
-3 meters/ per second^2

Answer 1

Do you know the meaning of average acceleration? It's the change in velocity per the change in time.\[\bar a=\frac{\Delta v}{\Delta t}=\frac{v_f-v_i}{t_f-t_i}\]

Answer 2

So that is \(\Large \frac{5\ [m/s]-0\ [m/s]}{10\ [s]-0\ [s]}=\frac{5\ [m/s]}{10s}\)

Answer 3

Oh! I see now :) Thanks for putting the formula! It helped a lot.
